RING-SPINNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 333,898, dated January 5, 1886.

Application filed August 21, 1885. Serial No. 174,930. (No model.)

To all whom it may concern.-

Be it known that I, GUSTAVUS E. TAFT, of Whitinsville, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Ring-Spinning Machines; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

In ring-spinning machines the cotton sliver passes from the front rolls through the guide- Wires to the spinning-spindle. When the spindles on a spinning-frame have the required quantity of yarn wound 011 the bobbins, these bobbins have to be removed by drawing the bobbin upward from the spindle. This process is called doffing. The guidewires are secured each to a narrow strip of wood hinged to a board extending the length of the spinning-frame, and have to be raised in succession to allow the bobbin to be raised off the spindle, or doffed.

This invention relates to means for raising all the guidewires of a spinning-frame simultaneously; and it consists in the peculiar construction of a rock-shaft and cams, as will be more fully set forth hereinafter.

Figure 1 is a front view showing the shaft, cam, and lever by which the hinged board, to which the several guide-wire boards are hinged, is raised, and the gravity-support. Fig. 2 is an end view showing the top and guide rails, the guide-wires, and the devices for raising the same in their normal position;

and Fig. 3 is an end view showing the guide rail and wires in'the raised position for doffing and the operating-lever held by the gravity-weight.

In the drawings, a is the top rail of a spinning-machine.

b is a board extending along the front of the top rail, a, to which it is secured by hinges.

c c are the short sections of wood in which the guide-wires d are secured. These pieces 0 c are each secured by a hinge to the board I), so that they can each be raised independent of the others, as is required in piecing up any broken threads during the process of spinning.

E is a shaft extending along one side of the spinning-frame, supported in the bearings e e. The shaft E is provided with the cams or arms f f, placed at intervals along the shaft, which bear against the plates b, secured to the 5 5 under surface of the board b.

To the end of the shaft E the hand-lever g is secured, to operate the shaft and bring the cams ff to bear against the plates b and turn the board b on its hinges, so as to lift the guidewires out of the way and facilitate the dotting, as is shown in Fig. 3.

h is a pendent weight, supported on the bracket K pivotally so as to swing laterally in the direction of the length of the frame and maintain its perpendicular position by gravitation. This weight is provided wit-h the hook i, in which the hand-lever g is supported when in the position shown in Fig. 3, and the guidewires with the boards I) and c are held in the raised position. By this construction, by moving the hand-lever g the pendent weight h yields laterally until the lever has passed the hook 2', when the gravity of the weight places the hook behind the lever, and holds the same in the locked position shown in Fig. 3.

As most ring-spinning frames are provided with twolines of spindles, being double frames, the devices for lifting the guide wires are placed one on each side of the frame. This arrangement not only saves much time in doffing, but avoids kinking the yarn which is caused by the old method of throwing the guide-hook backward over the board, which allows the yarn to form a loop into which the twist readily runs and forms a kink. By merely raising the guide-wire, as shown in Fig. 3, no loop is formed, and the twist does not run back beyond the guide-wire.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination, with the hinged board I) and the hinged guides c d, of the shaft E, the cams f f, the plates 1), the lever g, and gravity-support h, as described.

2. The combination,with the hinged guiderail 22, having the hinged guide-wire pieces a and the plates b, and the shaft E, having the cams ff, and operating-lever g, of the gravity- I00 support h, pivoted to the standard k, and having the hook i, for the purpose described.

GUSTAVUS E. TAFT.
